; BURR FOR KNITTING- MACHINES AND MEANS FOR SUPPORTING THE SAME.

SPECIFICATION forming part of Letters Patent No. 284,283, dated September 4, 1883,

Application filed October 4,1882. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE W. CUMMINGS, of Oohoes, in the county of, Albany and State of New York, have invented certain new and useful Improvements in Burrs for Knitting- Machines and Means for Supporting the Same, of which the following is a specification.

My invention consists in improvements in burrs of knitting-machines and in the spindles for supporting the same; and the objects of my improvements are, first, to provide proper facilities for lubricating said spindles without requiring. the stoppage of the machine and the removal of the burr severaltimes each day to effect that purpose; and, second,-to protectthe goods from becoming soiled by being brought into contact with the lubricant. I attain these ing for the said burr.

objects by means of the construction illustrated in the accompanying drawings, which form part of this specification, and in which- Figure 1 is a vertical section of a burr and spindle containing my improvements; and Figs. 2 and 3 are respectively side elevations of the sleeve and the spindle and its attached oil-cup. I

As represented in the drawings, A desig nates the knitting-machine burr for which Letters Patent of the United States No. 42,545 were granted toGharles Allardice on the-3d day of May, 1864. On the under side of said burr I form a pendent annular flange, B, for a purpose hereinafter set forth.

0 is aremovable sleeve fixed in the center of said burr, and provided with a closed top, 0. .The said sleeve is fixed in the burr A, so as to revolve with and form an elongated bear- The closed top 0 pre vents the lubricant from oozing out of the top bricant for the burr. The annular flange B of 5 the burr overlaps the upper edge of the cup E, thereby producing greater stability in the burr and preventing the admission of dirt and dust into the cup to pollute its contents. The lower end of the sleeve 0 extends downward, so as to bear upon the bottom of the cup E, and is immersed in-the oil in the said cup, which oil is carried, by the rotations of the burr, upward on the spindle D, and furnishes the required lubrication for the revolving burr. l 55 Whenpreferred, the removable sleeve 0 may 7 be omitted from the construction, and a permanent pendent collar formed .on the body of the burr may b'esubstituted for it; but preferably I construct the device with the removable sleeve, as hereinbefore sh own and described.

I claim as my improvement The combination with the burr A, provided with a pendent flange, B, as described, and65 the sleeve 0, provided with a closed top, a, of the spindle D, provided with an annular oilcup, E, all being constructed and arranged to operate as herein specified.

GEORGE W. CUMMINGS.
